87465355d3 Add repaint functions
Sometimes it is necessary for third party code to have a
function called during the redraw process, so that you can
update the scenegraph before it is painted.

b3fe1b8a8a [cogl-vertex-buffer] Ensure the clip state before rendering
Before any rendering is done by Cogl it needs to ensure the clip stack
is set up correctly by calling cogl_clip_ensure. This was not being
done for the Cogl vertex buffer so it would still use the clip from
the previous render.

Now that everything is float, the marsharlling function of the
size-change signal should reflect that fact.

a1b0160da7 [test-text-perf] Small fix-ups
- Fix a typo in a for loop in create_label which left 'i'
  uninitialised and caused a crash if you're unlucky.

- Set the CLUTTER_VBLANK=none environment variable.

- Don't quit on a keypress.

- Trailing whitespace tidy up.

7e18109f9b [cogl-pango-display-list] Use GL_TRIANGLES under GLES
GLES doesn't support GL_QUADS. This patch makes it use GL_TRIANGLES
instead in that case. Unfortunately this means submitting two extra
vertices per quad. It could be better to use indexed elements once
CoglVertexBuffers gains support for that.

5481681e5c Use the right internal format for GL_ARB_texture_rectangle
When ClutterGLXTexturePixmap uses GL_ARB_texture_rectangle,
it needs to pass the right internal format (GL_RGB or GL_RGBA)
when it initializes the texture with glTexImage2D() or later
handling won't recognize the alpha channel.

2c6719502a [actor_paint] Ensure painting is a NOP for actors with opacity = 0
Since it is convenient to use geometry with an opacity of 0 for input only
purposes it's a worthwhile optimization to avoid submitting anything
for such actors while painting.

f13c3ee309 Make backface culling work with vertex buffers
Backface culling is enabled as part of cogl_enable so the different
rendering functions in Cogl need to explicitly opt-in to have backface
culling enabled. Cogl vertex buffers should allow backface culling so
they should check whether it is enabled and then set the appropriate
cogl_enable flag.

3fc64dfaa7 [pango-render] Keep a reference to the first line to detect layout changes
In order to cope with the situation where an application renders with
a PangoLayout, makes some changes and then renders again with the same
layout, CoglPangoRenderer needs to detect that the changes have
occured so that it can recreate the display list. This is acheived by
keeping a reference to the first line of the layout. When the layout
is changed Pango will clear the layout pointer in the first line and
create a new line. So if the layout pointer in the line becomes NULL
then we know the layout has changed. This trick was suggested by
Behdad Esfahbod in this email:

085be4cebc [cogl-pango-render] Fix the positioning when calling cogl_pango_render_layout
When a position is given to cogl_pango_render_layout_subpixel it
translates the GL matrix by the coordinates. However it was not
dividing by PANGO_SCALE so the coordinates were completely wrong.

1985fa75b1 [texture] Use a box instead of int coordinates
Most of the operations involving the texture's allocated area require
floats -- either for computations or for setting the geometry into
COGL. So it doesn't make any sense to use get_allocation_coords() and
cast everything to floats.

1f1d19f634 [cogl] Move debugging to a configure-time switch
Currently, COGL depends on defining debug symbols by manually
modifying the source code. When it's done, it will forcefully
print stuff to the console.

Since COGL has also a pretty, runtime selectable debugging API
we might as well switch everything to it.

In order for this to happen, configure needs a new:

        --enable-cogl-debug

command line switch; this will enable COGL debugging, the
CoglHandle debugging and will also turn on the error checking
for each GL operation.

The default setting for the COGL debug defines is off, since
it slows down the GL operations; enabling it for a particular
debug build is trivial, though.

df1a9b7a74 [cogl] Rework the debug messages
COGL has a debug message system like Clutter's own. In parallel,
it also uses a coupld of #defines. Spread around there are also
calls to printf() instead to the more correct g_log* wrappers.

This commit tries to unify and clean up the macros and the
debug message handling inside COGL to be more consistent.

3115a61688 [cogl] Rework the GL-error-to-string conversion
The code for the conversion of the GL error enumeration code
into a string is not following the code style and conventions
we follow in Clutter and COGL.

The GE() macro is also using fprintf(stderr) directly instead
of using g_warning() -- which is redirectable to an alternative
logging system using the g_log* API.

cd3acca2b7 [build] Link Cogl against -lm

convenience library.

79cb0a3515 [animation] Remove InitiallyUnowned from Animation
ClutterAnimation currently inherits the initial floating reference
semantics from GInitiallyUnowned. An Animation is, though, meant to
be used as a top-level object, like a Timeline or a Behaviour, and
not "owned" by another object. For this reason, the initial floating
reference does not make any sense.

d8aa6827ee Don't build Cogl.gir against installed Clutter library
Passing:

 --library=clutter-@CLUTTER_FLAVOUR@-@CLUTTER_API_VERSION@

to g-ir-scanner, when building Cogl was causing g-ir-scanner to
link the introspection program against the installed clutter library,
if it existed or fail otherwise. Instead copy the handling from
the json/ directory where we link against the convenience library
to scan, and do the generation of the typelib later in the
main clutter/directory.
